Mathematical modelling

Please show step by step calculation for the following question

In a chemical engineering process, water vapour (H2O) is heated to sufficiently high temperatures that a significant portion of the water dissociates, or splits apart, to form oxygen (O2) and hydrogen (H2) : H2OH2+21O2 If it is assumed that this is the only reaction involved, the mole fraction x of H2O that dissociates can be represented b K=1xx2+x2px where K= the reaction equilibrium constant and pt= the total pressure of the mixture. If pt=3.5atm and K=0.04, determine the value of x that satisfies the equation. Choose any one of the methods discussed in the lecture. Validate your answer graphically using either Excel or Matlab.
